Los Angeles Times: The real climate change controversy: Whether to engineer the planet in order to fix it

"Most climate experts agree that the best way to keep global temperatures in check is to rapidly reduce emissions of carbon dioxide and other greenhouse gases by transitioning to clean energy sources. But scientists and policymakers are deeply divided over which forms of geoengineering also deserve serious consideration — and when the world might want to use them."

Khaleej Times: Climate change fight needs bold new ideas

"Climate change poses an unprecedented threat to humanity, one that appears increasingly likely to reduce global standards of living dramatically within our lifetime, and cause untold damage in the longer term. And, because addressing such a daunting planetary challenge requires radical approaches, there have been wide-ranging discussions about what the world must urgently do to limit the rise in global temperature to less than 1.5°C above pre-industrial levels."

Geoengineerin Monitor: Why is Geoengineering being discussed at UNEA, and how should civil society respond?

"It has been almost a decade after the landmark moratorium on all climate-related geoengineering was passed by the Convention on Biological Diversity (CBD) in 2010 and several years since the decision of parties to the London Protocol of the London Convention on marine dumping prohibiting ocean fertilization and potentially other marine geoengineering proposals. Today, geoengineering is on the agenda of another UN body: the UN Environment Assembly."

Project Syndicate: The Geoengineering Fallacy

"Geoengineering technologies are not yet deployable globally, but support for them is advancing fast, thanks to backing by powerful advocates eager to start experiments. But no silver bullet for climate change exists, and we must not abandon proven methods for the sake of a promise that one will be found."

The Guardian: Radical plan to artificially cool Earth's climate could be safe, study finds

"A new study contradicts fears that using solar geoengineering to fight climate change could dangerously alter rainfall and storm patterns in some parts of the world."

Irvine, P.; et al. (2019): Halving warming with idealized solar geoengineering moderates key climate hazards

Irvine, P.; Emanuel, K.; He, J.; Horowitz, L.; Vecchi, G.; Keith, D. (2019): Halving warming with idealized solar geoengineering moderates key climate hazards. In: Nature Climate change. DOI: 10.1038/s41558-019-0398-8.

"Solar geoengineering (SG) has the potential to restore average surface temperatures by increasing planetary albedo, but this could reduce precipitation. Thus, although SG might reduce globally aggregated risks, it may increase climate risks for some regions. Here, using the high-resolution forecast-oriented low ocean resolution (HiFLOR) model—which resolves tropical cyclones and has an improved representation of present-day precipitation extremesalongside 12 models from the Geoengineering Model Intercomparison Project (GeoMIP), we analyse the fraction of locations that see their local climate change exacerbated or moderated by SG. Rather than restoring temperatures, we assume that SG is applied to halve the warming produced by doubling CO2 (half-SG)."

Project Syndicate: Governing Geoengineering

"New technologies to combat global warming could complement reductions in greenhouse-gas emissions. But their potential impact is highly uncertain, and failure to govern their use properly could aggravate existing threats to international peace and security."

Call for Sessions: Securing sustainable futures. Designing, planning, and making decisions on policies, practices, and infrastructures under deep uncertainty

Deadline: 1. April 2019

"We are now inviting proposals for sessions related to the theme of ‘Securing sustainable futures’. Session proposals can focus on specific methods or approaches and how these are or could be used across different application domains, or instead focus on the treatment of deep uncertainty within a specific domain or context."
